Big numbers in the cloud

…but it’s also very centralized. I had harder to find any good figures for cloud hosts. Sorry for the raw links.

As in 140 million messages per day! Even though we are talking short text snippets (all else is handled by companies outside of Twitter), they need a few servers for this, but a far cry from Facebook, as it handles much more complex and spacious data..

GroupOn’s revenue: http://www.businessinsider.com/groupon-revenue-run-rate-2010-12

Facebook’s revenue: http://mashable.com/2011/01/17/facebooks-ad-revenue-hit-1-86b-for-2010/

“All told, Williamson said Facebook alone accounted for 5% of all online ad spend in 2010; she expects that number to rise to 8% in 2011.”

In other words a market worth 40B now and much more in the future, increasingly with ads viewed via mobile devices. I wonder why Facebook’s app doesn’t show ads yet. It no doubt will in the near future.
